MERCERlZlNG-MAGHINE.

SPEGIZEICATION forming part of Letters Patent No. 657,705, dated September 11, 1900.

Application filed January 11, 1900. Serial No. 1,059. (No model.)

T0 at whom it may concern/.-

Be it known that I, THOMAS McGoNNnLL, of Chester, Delaware county, Pennsylvania, have invented an Improvement in Machines for Mercerizing, &c.-, of which the following is a specification.

cerizing and otherwise treating yarn; and it consists of the improvements which are fully set forth in the following specification and are shown in the accompanying drawings.

It is necessary in the process of mercerizing yarn under tension that suitable means shall be provided for adjusting theyarn supports or sticks to stretch the skeins to the de sired extent and to maintain them under the requisite tension during the shrinking action which results from the process of treatment. The success of the process depends to a great degree upon the effectiveness with which this tension or stretching action is produced or maintained; and it is one of the objects of this invention to enable the tension to be applied with ease and facility and to any eX-- tent that may be desired and in a machine of large capacity.

It is another object ofmy invention to insure a uniform treatment of all the skeins, both in the extent of tension to which they are subjected and the extent to which they are treated by the liquor.

It is another object of my invention to maintain all metallic and working parts out of contact with the liquor, so that they may not be injured or affected thereby.

In the drawings, Figure 1 is a side elevation of a mercerizing-machine embodying my invention. Fig. 2 is an end elevation of the same. Fig. 3 is an end elevation illustrating a modification in the devices for adj usting the upper rollers; and Fig. 4 is a side elevation, on a reduced scale, of the machine shown in Fig. 3. V

A A are two longitudinal vats carried by a suitable frame A and separated at a substantial distance from one another to form an intermediate longitudinal space.

E designates a series of rollers projecting at each side into the vats A A through suitable stuifing-boxes b and driven by suitable powertransmitting devices located in the space between thevats. In the construction shown the rollers R are long rollers spanning the space between the vats A A and geared together by a train of gears 0. As shown, the gears O are driven at one end from the powershaft M through gears M M and to insure My invention relates to machines for meruniform driving throughout the long train of gears 0 power is transmitted to the other end of the train through the longitudinal shaft N, driven from the shaft M by the bevel-gears O O and transmitting power to the train of gears C at the other end through the gears ,O O P P, corresponding with the gears O O M M be used.

D is a longitudinal vertically adjustable Other forms of devices may of course and centrally-located frame, inv which a series of upper rollers E, corresponding with the rollers 13, are j ournaled in suitable hearings e.

F F are upright guides for the frame D, carried by the base-frame A Various devices may be employed for supporting the frame D and adjusting it and its rollers E with reference to the, rollers B. Such adjustment must, however, be positive and uniform throughout the length of the frame D, and the devices employed must be capable of resisting the tension to which the rollers are subjected in the mercerizing process. v

In the construction illustrated in Figs. 1 and 2 I have shown a series of vertical screws G, engaging internal threads in the frame D and journaled at the lower ends in the baseframe A, with the upper ends projecting through the stationary top frame or crosshead A and driven by suitable gearing. H H are longitudinal shafts journaled in the brackets h from thetop frame A and driven from a driving-shaft I through suitable gears I I I and driving the screws G through bevel-gears J J. I have shown a pair of screws G at each end and one intermediate pair; but more or less may be used, according to the size of the machine.

In the construction shown in Figs. 3 and 4 the adjustable frame D is connected with top frame A by oppositely-disposed togglej oints K K, which are operated by a transverse screw L, engaging threaded sleeves at the elbows of the toggles, so that by operating the screw the invention.

The skeinsto be treated are slipped over the outer ends of the pairs of upper or lower sticks, and the upper sticks are adjusted to the proper tension, which may be easily changed or regulated when necessary. The driving devices are operated to rotate the sticks and move the skeins through the liquor to the desired extent.

The devices employed for moving the adj ustable frame and its yarn-sticks enable the adjustment to be made with facility and perfect uniformity throughout and to any extent that may be desired, so that all skeins are subjected to uniform tension. As this tension is uniform and the sticks of one set are rotated at a uniform speed, it is apparent that the various skeins will be subjected to uniform treatment throughout, both in the extent to which they are treated by the liquor and the amount of tension to which they are subjected.

By journaling the lower rollers in fixed hearings in the vatand locating the gearing exterior to the vat and accomplishing the adjustment by the upper rollers all metallic and working parts are maintained out of contact with .the liquor.

What I claim as new, and desire to secure by Letters Patent, is as follows:

1. In a machine for mercerizing, &c., the combination of two independent longitudinal vats, a series of rollers extending into said vats on each side and journaled in fixed bearings driving devices for rotating said rollers located in the space between the vats, an upper longitudinal and vertically adjnstable frame, a series of rollers carried by said frame, and projecting at each side over the vats, and means to adjust said upper frame to or from the vats to regulate the distance between the upper and lower rollers and the tension to which the yarn is subjected.

2. In a machine for mercerizing, &c., the combination of two independentlongitudinal vats, a series of long rollers spanning the space between said vats and projecting into them on each side and journaled in fixed bearings, driving devices for rotating said rollers locatedin the space between said vats, an upper longitudinal and vertically-adjustable frame, a series of rollers carried by said frame, and projecting at each side over the vats, and means to adjust said upper frame to or from the vats to regulate the distance between the upper and lower rollers and the tension to which the yarn is subjected.

3. In a machine for mercerizing, &c., the combination of two independent longitudinal. parallel vats, a series of long rollers spanning the intermediate space between said vats and projecting into them at each side, gearing between said rollers located in said intermediate space, and a series of upper rollers projecting over said vats and lower rollers at each side.

4. In a machine for merceriz'ing, &c., the combination of two independent parallel lon= gitudinal vats arranged to form an interme diate space between them,a series of long rollers spanning the intermediate space, projecting at either end into said vats and journaledin stationary bearings, gearing between said rollers located in said intermediate space, an upper longitudinal and vertically-movable frame, a series of rollers carried by said movable frame and projecting over said vats and lower rollers at each side, and means to raise or lower said upper frame.

5. In a machine for mercerizing, &c., the combination of two longitudinal parallel vats arranged to form an intermediate space between them, a series of long rollers spanning said intermediate space, projecting into said vats at either side and journaled in station ary bearings, a train of gears between said rollers located in said intermediate space, driving devices operatively connected with said train of gears at one end, and power-transmitting connections between said driving devices and the other end of said train of gears.

6. In a machine for Inercerizing, &c., the combination of a vat to contain the merceriz ing liquor, a series of rollers projecting into said vat and journaled in stationary hearings in the sides thereof, a series of upper and adjustable rollers projecting over said vat and l in the sides thereof, driving devices for rotating said rollers in their stationary bearings located exterior'to said vat, a series of upper and adjustable rollers projecting over said vat and the lower rollers journaled therein, and means to adj ust said upper rollers to regulate their distance from the lower rollers and the tension to which the yarn is subjected.

8. In a machine for mercerizing, &c., the combination of a vat to contain the merceriz ing liquor, a series of lower rollers, an upper adjustable frame, stationary guides for said frame, a series of upper rollers carried by said upper adjustable frame, toggles between said adjustable frame and a stationary part, provided with threaded sleeves at the elbows, and screws engaging said threaded sleeves 10 provided with threaded sleeves at their elbows, and screws engaging said threaded sleeves for operating said toggles and adjusting the movable frame and its rollers relatively to the other set of rollers.

In testimony of which invention I have hereunto set my hand.
